How to send a message to DM or guild channel after listenCommand?

[Eowgik]

Hi.

I'm new to this.
Sorry for my English (I use a translator).

I started to create a bot for events (guessing riddles).

I created slash commands with parameters.
When listening to these commands, I can reply to the author or to the same channel.

$discord = new Discord([
    'token' => 'token_my_bot',
]);

$discord->on('ready', function ($discord) {
    //listening slash commands
    $discord->listenCommand('ans', function (Interaction $interaction) {
    //connect the database
    $database = new DatabaseGateway();
    //checking if a member is in a team, getting the answer to the task and comparing it with the member's answer, etc.
    ...
    //send message DM and delete message in channal
    $interaction->user->sendMessage($out);
    $interaction->respondWithMessage(MessageBuilder::new()->setContent("send  PM"));
    $interaction->deleteOriginalResponse();  
    });
});

$discord->run();

I save all members in the database (discord_id, nickname, team_id).
If the team member answered correctly, I want to send the next task to all the members of this team.
How can I do this?

Аnd another question, how to update a message in a special guild channel after a slash command of any of the members.
for example, registering a team or adding a member to a team. a message in a guild channel will display a list of members by team from the database.
